7.1 General safety notes
Personnel:
Skilled qualified electrician
DANGER!
Danger of electric shock! Do not touch any live com-
ponents! Electrical equipment carries a dangerous
electrical voltage.
–
Only skilled qualified electricians are allowed to
work on the electrical system.
–
Switch off the power supply before working on
any electrical equipment.
7.2 Wiring and connection to the cen-
tral BMS
Supply voltage
The smoke control damper may be equipped with a
230 V AC or a 24 V AC/DC actuator. See the per-
formance data on the actuator rating plate.
Several actuators can be connected in parallel as
long as the performance specifications and
switching thresholds are taken into consideration.
Make electrical connections according to the exam-
ples below.
Auxiliary switch
During application, it must be ensured that the con-
tacts of the auxiliary switches can no longer be used
in the milliampere range once they have been wired
up to a relatively high current.
A combination of mains and protective extra-low
voltage is not permitted for the auxiliary switches.
Functional integrity of electrical wiring systems
Electrical wiring systems for supplying power to smoke
control dampers, for example in mechanical smoke con-
trol systems and pressurisation systems, must be
designed with a functional integrity of at least 90
minutes. If electrical wiring systems are installed in
safety stairwells, functional integrity must be guaranteed
for at least 30 minutes.
Actuators with 24 V AC/DC
Safety transformers must be used. The connecting
cables are fitted with plugs. This ensures quick and
easy connection to the TROX AS-i bus system. For con-
nection to the terminals, shorten the connecting cable.
